Mobile communication base station radio frequency signal sector switching system

Abstract

The invention discloses a mobile communication base station radio frequency signal sector switching system. The switching system is arranged between base station radio frequency interfaces and base station antennae of a wireless communication base station, and comprises base station interfaces, antenna interfaces and a switching circuit, wherein the base station interfaces are connected with the three base station radio frequency interfaces in the wireless communication base station; the antenna interfaces are connected with the three base station antennae; and the switching circuit is positioned between the base station interfaces and the antenna interfaces, can realize simultaneous electrical connection between any base station interface and one, two or more antenna interfaces and between any antenna interface and one, two or three base station interfaces, and consists of radio frequency switches and triple power division combiners. The mobile communication base station radio frequency signal sector switching system provided by the invention can allocate the carrier frequency of an idle sector to sectors with relatively higher telephone traffic in the same base station on the premise of keeping invariable conventional base station antenna configurations so as to improve the channel utilization rate of the idle sector, reduce the channel congestion state of the sectors with the relatively higher telephone traffic, improve the comprehensive quality of a mobile communication network and avoid the wasting of carrier frequency resources in the conventional mobile communication base station, and has the advantages of energy saving and environmental friendliness.

Description

technical field [0001] The application of the present invention relates to a radio frequency signal sector switching system of a mobile communication base station, which belongs to the technical field of wireless communication. Background technique [0002] Radio frequency is referred to as RF, which is an abbreviation of high-frequency alternating electromagnetic waves. The alternating current that changes less than 1,000 times per second is called low-frequency current, and the one that changes more than 10,000 times is called high-frequency current, and radio frequency is such a high-frequency current. In the theory of electronics, when current flows through a conductor, a magnetic field will be formed around the conductor; when an alternating current passes through a conductor, an alternating electromagnetic field will be formed around the conductor, which is called electromagnetic wave. When the electromagnetic wave frequency is lower than 100khz, the electromagnetic w...
